GUN-CLEANING DEVICE.

SPECIFICATION forming part of Letters Patent No. 471,477, dated March22, 1892. Application filed September 30, 1891- Serial No. 407,265- (Nomodel).

To all whom it may concern:

Be it known that I, GEORGE H. GARRISON, of Kent, in the county of Kingand State of Washington, have invented a new and useful Improvement inGun Swabbing or Cleaning Devices, of which the following is a full,clear, and exact description.

This invention more especially relates to the rod which actuates theswab or cleaner proper for wiping out the interior of the barrel of agun.

The object of the invention is to adjust the swab or cleaner by director independent pressure to any required size, so as to exert thenecessary pressure against the sides of the barrel after the cleaner hasbeen projected or put into the gun; and the invention consists in agun-cleaner rod of novel construction, including attached adjustingmeans, whereby the above-named object is very efficiently andexpeditiously obtained, substantially as hereinafter described, and moreparticularly pointed out in the claims.

By this invention the great objection to other gun-cleaning devicesgenerally is avoidednamely, the unsatisfactory adjustment when thepressure to act upon the sides of the barrel is produced'by tighteningup the cleaneras, for instance, by a screw-before putting the cleanerinto the barrel, and which when the adjustment is made to adapt thecleaner to fit the breech of a gun makes it too large when shoved downtoward the muzzle in choke-bore guns, thus requiring new or repeatedadjusting.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents an exterior longitudinal broken view of a gunswabbing or cleaning device embodying my invention andcomprising atubular main or outer rod or stick and an inner longitudinally-movablerod, both shown as constructed in three sections or lengths, with a swabapplied to the forward end of the front outer member and a lever appliedto the rear member or handle portion of the device for moving the innerrod forward to give the necessary pressure to and lateral distension ofthe swab. Fig. 2 is a longitudinal central section, upon a larger scale,extending from 2 to'2 in Fig. 1 of the forward portion or front sectionof the whole device, including the swab or cleaner. Fig. 3 is a furtherlongitudinal section of the intermediate and rear members in part of thewhole device; Fig. 4, a longitudinal sectional View of the rear memberin part of the whole device with attached lever for actuating the innerrod; Fig. 5, an exterior longitudinal view of the portion shown in Fig.4, looking in a plane at right angles to the latter figure; and Fig. 6is a transverse sectional view upon the line 6 6 in Fig. 5, omitting thelever and central or inner rod.

While the device is here shown as constructed in three main sections orlengths detachably jointed together, it is not necessarily restricted toany number of such sections or pieces. I prefer, however, to make it inthree pieces, and it will here be described accordingly.

A A A indicate the three members or lengths of the outer rod, which ishollow or tubular and supposed to be made of wood. Said members orlengths are detachably connected together at their meeting end joints byscrew-threaded metal ferrules b o, and the front member A is fitted witha cap-like ferrule d, extending above it and of reduced diameterexternally for a portion of its length to receive over it alongitudinally-sliding compressing-ferrule B, which, when forced forwardor outward, serves to produce lateral distention of the swab C to giveit the neces sary pressure on the sides of the barrel. To this end theswab or cleaner 0 is or may be supposed to be made of felt or other softand flexible material, with a screw e passing centrally through it andengaging at its inner end with the cap-like ferrule d, which is fast onthe outer member A. The head of this screw, or washer under its head,binds the swab at its outer end, while a washer f and nut g, screwingover and passing beyond the threaded end of the screw, act as a followeron the inner end of the swab and lie against the outer end of thesliding compressing-ferrule B, so that when the latter is forced outwardthe swab will be distended or expanded lat-' erally, as required.Instead of a felt swab, a

cloth-covered rubber one similarly bound and held might be used, or awell-known split metallic one be readily remodeled to conform foroperation in like manner. In fact, I do not restrict myself to anyparticular material of which to construct the swab.

The direct pressure to expand the swab laterally after it has been putinto the barrel of the gun is produced by the longitudinallymovableinner rod, which lies centrally within the main or outer rod, and ishere shown as also constructed in three sections or lengths D D D" toconform to the members A A A These rod-sections areguided in theirlongitudinal movement and restrained from falling out of theirrespective outer-rod sections when the outer rod is disjointed byrivets, pins, orscrews 7t passing transversely through the outer rod orits ferrules and throughslots i in the inner-rod sections. The severalinner-rod sections are preferably made to center with each other attheir meeting ends, as shown at k in Fig. 3, and so that they willvirtually form a straight continuous rod. The front section or lengthD'of this movable rod is hooked on or engages witha transverse pin orscrew Z, applied to the compressing-ferrule B and passing through sideslots on m in the caplike ferrule cl, on which the compressingferrule 13slides. This provides for the outward movement of thecompressing-ferrule to laterally expand or distend the swab C byprojecting the inner rod D D D forward, and so producing endcompressions on the swab, which swells it out laterally, as shown bydotted lines in Fig. 2. Such outward movement of the inner rod iseffected by applying force to the back end of the section D of saidrod-as, for instance, through a cam-lever E, applied to a split strap onthe rear member A of the outer rod and working at its cam end within arecess it in said member, the cam portion of the lever bearing againstthe back end of the rod-section D and being held there and theworkingparts in place ready for operation by a spring G, arranged between astop-collar s on the inner-rod section D, and a loose collar 5'', havinga suitable bearin g or. stop in the front main member A.

By means of this device it will be seenthat the swab or cleaner may bereadily entered within the gun and be distended or spread laterally bydirect pressure applied to it after it has been put into the gun and beadjusted to give any required pressure against the; sides of the barrel,it only being necessary in order to accomplish this to apply therequisite force to the back end of the inner rod to move it forward,while the outer rod is held firmly by the hand, and this may readily bedone by pressing with more or less force on the handle portion ofthecam-lever E against the tension of the return-spring G.

If required to change the length of the whole device, the middle sectionof the outer rod, with its contained inner-rod section, may

be disjointed and removed and another like section of outer and innerrod of the necessary or changed length be substituted therefor.

Any standard gun-cleancr as now made can be used when desired on theouter or main rod without the inner-rod direct-pressure attachment.

The several ferrules which are fitted onto the ends of the woodenmembers of the outer rod may be secured thereon by screw-threads cut onthe ends of said wooden members, and

the ferrules may be made to fit said screwthreads, or the ferrules maybe secured to their places by cross pins or rivets or otherwise.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-.

In gun swabbing or cleaning devices, the combination of a tubularmain outer rod adapted to carry the swab or cleaner on its forward endand a longitudinally: movable inner rod adapted by applying force toindependen tly move the inner rod forward to produce a direct andindependent pressure on the swab or cleaner to expand or distend itlaterally.
